Na eagled the par-5 first hole Friday on the way to an 8-under 62, his third score at least that good in the past six rounds on the cozy course made famous by Ben Hogan. Na, tied for second at 8 under with first-round leader Tony Finau, trailed Jonas Blixt by one halfway through Colonial.

After opening with a 62 and closing with a course record-tying 61 to finish fourth last year, Na followed the eagle with six birdies in a bogey-free round after being happy to shoot par 70 on a windy afternoon in the first round.
